Thiocyanation and 2-Amino-1,3-thiazole Formation in Water Using Recoverable and Reusable Glycosylated Resorcin[4]arene Cavitands

A family of three spatially directional resorcin[4]arene cavitand glycoconjugates (RCGs) have been applied as efficient recoverable and reusable inverse phase transfer catalysts for eco- A nd environmentally friendly thiocyanation and 2-amino-1,3-thiazole formation reactions in water. The results show that RCGs (1 mol %) were capable of hosting and catalyzing various water-insoluble bromo/thiocyanato substrates in water without the use of any co-organic solvents. The recoverability and reusability of RCG catalytic systems, that is, RCG1 and RCG3, were also examined upon a simple extraction of the desired products using DCM or ethyl acetate, followed by subjecting the recovered aqueous solution containing the RCG catalysts to the next reaction cycles.

Reaction of Guanidinium Salts with Alkyl Bromides and Acid Chlorides

The guanidinium salt 1a reacts with alkyl bromides 2a-g and acid chlorides 2h-k to give the nitriles 3a-g and the acyl cyanides 3h-k, respectively.Acyl isocyanates 4a,b have been obtained from the guanidinium cyanate 1d and the acid chlorides 2h,l.Reaction of the alkyl bromides 2b,c,m,n and acid chlorides 2h,l with the guanidinium thiocyanate 1e affords alkyl thiocyanates 5a-d and acyl isothiocyanates 6a,b, respectively.
